Dreamscape (Dream eater ap) error

I lied down on the guildhall bed. And there were 2 options. 1 to go the nightmare zone, the second to go to dreamscape zone. So i've tapped on the dreamscape button which brought me to the dreamscape zone. THEN POOF "Shutdown in 15min" soo i've got kicked out of there. And now after the update i can't go to the dreamscape zone anymore (FYI i'm lvl 71, so i cant buy it anymore for 250g). The only option that it'll give me is the nightmare zone option.

Please help!

Try tomorrow, the quest can be done only once a day.

Wonderfull!! thank you for your quick answer :)
